Nrran STATES JAMES F. THAYER, OF PROVIDENCE, RHODE ISLAND.

MACHINE FOR SECURING BUTTONS TO FABRICS.

SPECIFICATION forming part of Letters Patent No. 337,636, datedMarch 9,1886.

Application filed January I, 1886. Serial No. 187,869. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. THAYER, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Machinesfor Securing Buttons to Fabrics; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to an improvement designed for use on machinesfor securing but-- tons to fabrics by means of metallic fasteners, onemember of said machine holding the button or button and fastening, whilethe other is operated by suitable power to secure the button andfastening to shoes or other articles. In machines of this characterheretofore made there have been no provision for the removal of thebutton and fastener from the holding member after being secured to theshoe or other article except by forcibly ejecting the same from themachine by hand, which method of removal is attendedwith seriousdifficulties, as it is of the utmost importance that the clinchedfastener and button be re moved previous to placing the next button inposition forattachment.

To this end my invention consists, primarily, in providing the buttonand fastenerfeeding mechanism with a movable pawl or ejector soconstructed and operated in connection with said feeding mechanism thatthe clinched fastener and button will be ejected from the holding memberof the machine previous to placing the next button and fastener inposition for attachment to a shoe or other article, all substantially ashereinafter more fully described, and pointed out in the claims.

To illustrate the operation and use of my improvement I have shown anddescribed in the accompanying drawings and specification my invention asapplied to the machine patented January 20, 1885, by J. O. F. Dick, No.310,934, to which I refer for a full detail of the entire machine.

In the accompanying drawings, Figure 1 is a front View in partialsection of the head of the machine, showing the location of myimprovement. with relation to the feeding mech anism and clinchedfastener and button; Fig. 2, alike view showing the ejector in positionfor removing the button and fastener at the next movement of the feedingmechanism. Fig. 3 represents the same with the ejector in the act ofremoving the clinched fastener and button; Fig. 4, a top plan View ofthe ejector as attached to the feeding mechanism; Fig. 5, a sideelevation of the ejector-provided with an adjustment. Fig. 6 is a sideelevation of the upper portion of the stationary head of themachine,showing thelocation of the ejector with relation to the slot inthe same. Fig. 7 is a cross-sectional view of'the inclined raceway.

In the drawings, D represents the head of the button-attaching machineshown in the patent to Dick, referred to, corresponding in a general waywith the upper or button-hold ing jaw of a hand instrument, constructedrigidly upon a standard. To one side of the head is secured an inclinedraceway or chute, E, composed of two parallel sections, affording alongitudinal slot, through which the button and fastener are moved bytheir own gravity, the button-stop i arresting their progress in saidraceway. The bell-crank lever Z is pivoted to the head D, as shown, andis operated at its upper end by the cord a through the medium of therear portion of the reciprocating jaw O,'which clinches the fastenerwhen operated upon by the treadle or other suitable power. At the lowerend of the bellcrank lever Z is pivoted the feeding-finger K, which iscarried rearward and forward by said bell-crank lever. This comprisesthe feeding mechanism of this machine, the outer end of the finger Kdropping behind abutton when the treadle is at its downstroke, and uponthe upward stroke the finger K moves the button longitudinally along theslot in the raceway E into position in the head D for clinching, whichis accomplished by the jaw C. On this feeding-finger K,I have placed myimprovement, in the present instance secured at the outer end by thepivot a. This iml provement consists of a movable pawl-shaped ejector,a, pivoted, as described, to the feedingfinger K, and is operated bysaid finger, as shown in the drawings. The pawl-shaped ejector a liesloosely over the but-ton when it is being secured to the shoe or otherarticle, as shown in Fig. 1.

After the first button is seen red to the shoe or other article, thefeeding'tinger K is moved rearward by the power applied, which causesthe ejector a to ride lightly over the clinched button until its outerend is at the rearof said button and the end of the feeding-finger K hasdropped back of the second button in the raceway, as shown in Fig. 2.

The next movement of the machine causes the feeding-finger K to moveforward longitudinally on the raceway, carrying with it the secondbutton, and forcing the ejector (4 against the rear of the first button,and as the forward movement is continued ejects said button and clinchedfastener from the holding member of the machine, as fully shown in Fig.3, the feed ing-finger leaving the second button in position forattachment at the completion of the movement.

The pivoted portion of the cjcctora maybe provided with an adjustablescrew, as shown in Fig. 5, so that the distance the button is ejectedfrom the holding member may be regulated. This renders the ejectoruseful in spacing the distance between each button attached without thenecessity of marking the shoe or other article to which the button is tobe secured.

As previously stated, I have shown and de scribed my improvement inconnection with this particular machine for ejecting a clinched buttonand fastener. It is evident,that without departing from the constructionof my improvement materially, the ejector may be used with like resulton any of the various machines for secui ing buttons now in use, andalso on machines for securing lacing hooks, staples, or other similardevices which require a feeding mechanism to place them one by oneinposition for attachment; to material, and in which it is required toremove the first de vice secured to make room for the second.

The ejector a may be pivoted to the feedingfinger K in any convenientplace, back from the end, so long as not to disturb the relation betweenthe ends of each, with regard to the button to be fed from the raceway.The outer end of the ejector is preferably made concaved, as shown, orangular, to retain a more firm hold on the under edge of the button inejecting the same from the raceway.

Having described my invention, I claim- 1. In eon'ibination with thefeetlingdinger of a button-attaching machine, a movable button ejector,as arranged with relation to said feeding mechanism, to precede thelatter and eject the button previous to feeding the next button into theholding portion ot'the machine in position to be attached to i'naterial,all substantially as herein set forth.

2. In a machine for attaching buttons to fabrics, and in combinationwith the buttonfeeding mechanism of said machine, a movable pawl orejector, as constructed and arranged with relation to said feedingmechanism as to precede the same and eject from the attaching portion ofthe machinethe attached button before feeding the next succeeding buttoninto position for attz'ichment.

3. In combination with the feeding mechanism of a lmtton-attachingmachine, a movable pawl or ejector, said pawl or ejector provided withalougil udinal adj ustment constructed to precede the feeding mechanismand eject a button from the holding member of the machine a greater orless distance from said holding member, substantially as herein setforth.

4. The combination, substantially as herein described, of a slottedstationary button-holding jaw jn'ovidcd with an int-lined raceway orchute having a longitudinal slot communicat' ing with theslot in theholding-jaw, a feeding fiuger provided with a movable lmttonejcctor,arranged to precede said fcedinglingcr and eject the first buttonsecured previous to the placement in snid holding-jaw ofthe nextbutllOll t0 b8 StUlll'Uil.

In testimony whereof I affix my signature in the presence of twowitnesses.

JAMES F. THAYER.
